HINGED JOINT Filed Jan. 28, 1928 Patented July 22, 1930 UNITEDsrAEsrATENT OFFICE v ALBERT JAMES COOPER, OF FINGHLEY, LONDON, ENGLANDHINGED JOINT Application filed January 28, 1928, Serial No. 250,271, andin Great Britain February 2,1927.-

This invention is forimprovements in or relating to hinged joints, andhas for one of its objects to cheapen the cost of manufacture of hingedjoints, and for another object to facilitate the assembly of the membersof hinged joints. The invention is particularly adapted for embodimentin tin boxes, but it is also capable of other applications.

Another object is toprovide a strong and neat hinged joint which can becheaply made and the parts of which can be readily assembled;

A further object is toprovide an improved is and robust construction ofjoint whereof one of themembers is formed with two housings for thereception of the hinge-pivot and is slit to permit parts of the memberto be separated for the insertion of the hinge-pivot and 2e afterwardsclosed together to hold the hingepivot in position. T

The following is a description of some forms of tin boxes to which thisinvention has been applied. Reference is made to the acwithout the lidafter it had been subjected to companying drawings in which V Figure 1is a perspective view of a box prior to the assembly of the hinged lidand shows a slit formed at two of the adjacent boundary edges of one ofthe housings for the hinge pivot. I f

Figure 2 is a similar view to Figure 1, and shows the ofi'set portion ofbox extending to outer end of the slit. 7 v

Figure 3 is a perspective View showing the horizontal part of the slitsituated between the housing and the edge of the box.

Figured shows the construction of Figure 3 as it would appear withoutthe lid after the final operation of assembling the latter art.Referringfirstly to Figure 1, it will be seen that the lid 1 has formedon the rear wall 2 of the rim an inverted T-shaped extension 3 the armsof which are bent to form the hinge pin 1. The rear wall 5 of the body 6of the box is formed with two bridge-like housings 7 and 8 each with oneopen and one blind end whereof the open ends are directed towards eachother. The material 9 of the wall 5 between the housings is offsetinwardly in order to permit the hinge pivot to work freely. A slit 10 isso formed as to extend along the top horizontal boundary of the housing7 8 parallel to the axis of the hinge and joins the vertical edge 11left by the formation of the open end of the housing. With thisarrangement the housing can be sprung outwardly to form a gap 12 whichpermitsthe insertion of the pivot pin.

In Figure 2 the offset material between the housing is made to extend tothe outer extremity 13 of the horizontal part of the slit; the insertionof the pivot pin is thus rendered more easy. i

In Figure 3 the horizontal slit 10 is located between the boundary edge14 of the housing 8andthe top edge 15 of the box and a vertical slit16extends upwardly at right angles to the axis of the hinge from the edge11 to meet the horizontal slit; the housing is thus provided with anextension 17 which may be sprung outwardly to form a gap 18 for theinsertion of the pivot pin. j i

' Figure 4 shows the box as it would appear the final operation inassembling the lid. 1 The top part of the offset material has beenstraightened out so as to leave beneath ita recess 19 for the hingepivot and the extension17 has been pressed inwardly to lie in the planeof the side of the box. 1

In all of the constructions illustrated, the material of the body of thebox is left without any slits extending from the aforesaid slits whichare adjacent to the housing 8, to the edge of the body of the box, andby this means a strong joint is produced. 7

1. A hinged joint having a hinge pivot carried by one member of thejoint and aligned, open-ended bridge-like housings so placed on theother member of the joint as to receive the ends of thepivot, and thematerial adjacent to at least one housing slit to permit the passage ofthe hinge pivot into the housings but left unslit through atleast' onehalf of the outline of the housing and also left without any slitsextending to an edge of the hinge member, for the purpose specified.

2. A hinged joint having a hinge pivot integral with one member of thejoint and aligned, open-ended brid e-like housings so placed on theother member of the joint as to receive the ends of the pivot, suchhousings being formed by indenting the material of the hinge member andslitting it to form apertures to the housings, and the material adjacentto at least one housing being slit to permit the passage of the hingepivot into the housings but being left unslit through at least twoadjacent sides of a rectangle bounding the housing and also being leftwithout any slits extending to an edge of the hinge member, for thepurpose specified. 1

3. A hinged joint having a hinge pivot carried by one member of thejoint and aligned, open-ended bridge-like housings so placed onthe othermember of the joint as to receive the ends of the pivot, and thematerial adjacent to one only of the said housings slit in such manneras to allow the housing to move so that the hinge pivot may be placed inoperative position, but left unslit through at least one half of theoutline of the housing and alsoleft without any slits extending to anedgeof the hinge member and the material between one housing and theslit adjacent to the other housing oli'set inwardly away from theplaneof the body of the hinge member, for the purpose specified.

4. A hinged oint having a hinge pivot carried by one member of the jointand aligned, open-ended bridge-like housings so placed on the othermember of the joint as to receive the ends of the pivot, and thematerial adjacent to at least one housing slit to permit the passage ofthe hinge pivot into the housings but left unslit through at least onehalf of the-outline of the housing and also left without any slitsextending to an edge of the hinge member, a portion of the slit in thematerial at the said situation adjacent to a housing lying substantiallyat right angles to the axis of the hinge pivot and the remainder of theslit lying along-the direction of the length of the said axis, for thepurpose specified.

5. A hinged joint having a hinge pivot carried by one member of thejoint and aligned, open-ended bridge-like housings so placed'on theother member of the joint as to receive the ends of the pivot, and thematerial adjacent to at least one housing slit to permit the passage ofthe hinge pivot into the housings but leftunslit through at least onehalf of the outline of'the housing and also left without any slitsextending to an edge of the hinge member, a portion of'the slit in thematerial at the said situation adjacent to a housing lyingsubstantiallyat right angles to the axis of the hinge pivot and theremainder of the slit lying along the direction of the length of thesaid axis, and said lastnamed portion of the slit being locatedsubstantially along the junction of the housin and the body of the hingemember, for the purpose specified.

6. A hinged joint having a hinge pivot carried by one member of thejoint and aligned, open-ended bridge-like housings so placed on theother member of the joint as to receive the ends of the pivot, and thematerial adjacent to at least one housing slit to permit the passage ofthe hinge pivot into the housings but left unslit through at least onehalf of the outline of the housing and also left without any slitsextending to an edge of the hinge member, the material of the hingemember adjacent to the open end of a housing being offset in thedirection away from the hinge pivot, and a portion of the slit in thematerial at the said situation adjacent to a housing lying substantiallyat right angles to the axis of the hinge pivot and the remainder of theslit, lying along the direction of the length of the said axis, and theaforesaid offsetting being continued along the length of thestrip ofmaterial between the lastnamed part of the slit and the adjacent edge ofthe hinge member, for the purpose specified. i r

7. A hinged joint having a hinge pivot carried by one member of thejoint and aligned, open-ended bridge-like housings so placed on theether member of the joint as to receive the ends of the pivot, and thema terial adjacent to at least one housing slit to permit the passage ofthe hinge pivot into the housings but left unslit through at least onehalf of the outline of the housing and also left without any slitsextending to an edge of'the hinge member, the material of the hingemember throughout the distance between two housings which have theiropen ends facing each other being offset in the directionaway from thehinge pivot, and a portion of the slit in the material at the saidsituation adjacent to a housing lying substantially at right angles tothe axis of the hinge pivot and the remainder of the slit lying alongthe direction of the length of the said. axis, and the aforesaidoffsetting being continued along the length of the strip of ma terialbetween the last-named part of the slit and the adjacent edge ofthe'hinge member, for the purpose specified.

In testimony whereof I affix my signature.
